[ NOTICE ]
since i have changed the kernel version string stock wifi modules will no longer work on my kernel...
if u try to enable them on new kernel (v7 onwards) u will get "ERROR" while starting WIFI...
i will be providing wifi modules for my kernel which HAVE TO BE FLASHED VIA RECOVERY for wifi/bt to work correctly
stock wifi modules will also be provided which again will have to be flashed via recovery if u want to return to stock kernel OR if u revert to older v06 or lower kernels
remember i have already told this to u guys... if i see some users reporting that wifi is giving error because u did not follow my instructions ur post WILL BE IGNORED....
save the boot.img in the folder with fastboot binaries (fastboot.exe files)
save the wifi modules update.zip to sdcard (on phone)
power down device
start device in fastboot mode
use the following command to flash the boot.img
Code:
fastboot flash boot boot.img
reboot phone and enter recovery
flash the wifi modules update.zip for my kernel
reboot phone and enjoy the kernel
[ how to get back to stock kernel OR older versions of my kernel (v06 and lower) ]
download the stock wifi modules update.zip
extract the kernel.sin (or boot.img if u want to flash my older kernels) file from the stock FTF u used to flash this fimware
save the kernel.sin (or boot.img if u want to flash my older kernels) in the folder with fastboot binaries (fastboot.exe files)
save the wifi modules update.zip to sdcard (on phone)
reboot phone and enter recovery
flash the stock wifi modules update.zip
power down device
start device in fastboot mode
use the following command to flash the kernel.sin (or boot.img if u want to flash my older kernels)
Code:
fastboot flash boot kernel.sin
reboot phone and thats it u should now be on stock kernel (or my older kernel)
FOR OVERCLOCKING
start SetCPU/NoFrills CPU Control app on ur Play (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
SLOWLY increase the frequency one notch at a time and do stability/testing for few hours
if u feel that this work has helped u OR u think that the work i put into making this is worthy of donations, then click on the following link for buying me some coffee/beer/etc
hey guys here i am attaching a template update.zip which has been tested to work on the recovery provided here... u can add ur stuff to that file and edit the updater-script so that the u can flash ur files via this recovery...
basically it contains the correct combination of update-binary & mounting syntax...
this file is NOT required for normal/general users
thank you if2 for posting ur sources (for acpu file) and allowing me to work on it for Xperia Play! guys if u like this please dont forget to thank him!
special thanks to axiomjunglist for helping out with beta-testing

[ wht is overclock? ]
"Overclocking is the process of running a computer component at a higher clock rate (more clock cycles per second) than it was designed for or was specified by the manufacturer, usually practiced by enthusiasts seeking an increase in the performance of their computers." - Source: Wikipedia
so it is pushing the boundaries posted by the manufacturers of the device to gain more performance!
BUT performance comes at a price! OVERCLOCKING can be and IS harmful to the device... prolonged use can cause hardware faults including the cpu chip getting fried!
ok time for some gyan!
see each cpu/chip is different
each is unique and has different tolerances
so dont directly jump to max frequency
slowly keep increasing the frequency
check its stability for 5-10 hrs
check for random reboots
check which one is best suitable for ur device
if u start getting reboots/OS freezes/device starts becoming too hot then throttle back and use lower frequencies
remember just because someone elses device was able to work at that frequency doesnt mean that ur phone can support/handle that frequency
YOU HAVE BEEN WARNED
[ wht is prerooted kernel? ]
well this kernel removes the security checks (atleast from ramdisk); su binary & superuser.apk will automatically be installed by kernel! no need to flash any additional zips or use one-click rooting apps! this kernel has it all in-build
[ features ]
prerooted
kernel is insecure (ro.secure=0)
su binary & superuser.apk will automatically be installed by kernel (thanks to Bin4ry for posting the file RootXperia.zip; i have used the superuser files from his zip)
busybox already installed in /sbin/
adb server is persistent
usb debugging enabled
rootfs and /system mounted as rw (thank you Blagus for the tip )
CWM recovery (Thanks to FreeXperia team)
ability to take backup/restore of ur ROM
flash any update.zips
lots more }
overclocking
set bootup frequencies from 245 Mhz to 1 Ghz
so that ur device boots safely and u can use the kernel as is w/o overclocking
for using the additional frequencies u will need a program like SetCPU
frequencies unlocked in kernel from 128 Mhz to 1.86 Ghz
voltages for standard frequencies are stock, for nonstandard frequencies (1Ghz+) voltage has been increased
compiled the kernel from stock SE sources with acpu file provided by if2
modified the stock ramdisk for this to function as per requirement
added Recovery files to ramdisk from ramdisk of boot.img from anzu_beta_FXP014 release
added su binary & Superuser.apk right inside kernel-ramdisk
[ so why should u bother? ]
well now u wont need to download huge prerooted system.img files (150-250 MB files), u can just use download this small kernel (~6MB) which is prerooted with working recovery
overclocking will help the device perform faster in games/benchmarks (IT IS RECOMMENDED THAT U DO NOT OVERCLOCK UR DEVICE FOR A LONG TIME, throttle it back to stock frequencies once u finish ur "high performance requiring task" :P)
[ how to install ]
download the boot.img
save the boot.img in the folder with fastboot binaries (fastboot.exe files)
power down device
start device in fastboot mode
use the following command to flash the boot.img
Code:
fastboot flash boot boot.img
reboot phone and enjoy the kernel
FOR OVERCLOCKING
start SetCPU app on ur Play (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
SLOWLY increase the frequency one notch at a time and do stability/testing for few hours
if it get flashed properly and the device boots up check the Menu -> Settings -> About Phone -> Kernel Version
it should say something like the screenshot posted above... (thank you axiomjunglist for the screenshot)

i am slightly confused... did u test it on stock firmware or CM7?
also can u please post the About Phone screenshot (like the one i posted in 1st post) so that i can update 1st post with it!
thanks!
Stock firmware. I was on stock kernel with stock rom, bootloader unlocked, and rooted. Flashed the boot.img after making a recovery backup and was in business

Does this break camera on stock rom like blagus his kernel?
In my experience with the cm7 kernel it's best to set it at 245MHz-1.4GHz if you like to run it conservative. Ondemand had the clockspeed nearly always on full speed, but with conservative lower then 245MHz makes the homescreen, app drawer, menu's etc. feel slower. With 245MHz this is much less. 1.5GHz made my device feel a little bit to warm while gaming for my taste, quickly resulting in sweaty fingers. Progbably because my case keeps it quite warm. 1.4GHz has this problem MUCH less in my case. I hope this helps.
Does this break camera on stock rom like blagus his kernel?
Camera and wifi both working! Cheers DooMLoRD, this is a sweet kernel patch. I am really digging this. So far totally stable at 1516MHz... for now I will keep it there and run this overnight to get a true indication of stability.
Flashed the Kernel and can confirm axiomjunglist’s impression, everything works (Wifi, Camera etc.)
The first feeling about it was, that the touchscreen sensibility has noticeable increased, just as excepted.
I have tried to test out the 1.51 ghz frequency and I slipped accidentally to the max scale….lol.
It immediately crashed of course. Afterwards, I was able to run it stable at 1.51 ghz.
Well, I’m looking forward for the 1.86 ghz until the end of the week. But I will be definitely more careful now, with my clumsy finger ^^
Stable so far, will report back. Thank you deeply Doom & if2.
